Setting up and operating the BUC system
Block Up Converter Systems 6700/6900 series User Guide 67
Set transmit
attenuator
Sets the transmit attenuator
of the BUC in dB.
To minimise the possible
effects of interference it is
preferable to have a high
transmit attenuation and a
high IF level from the
modem. Therefore, the BUC
attenuator should be set as
high as possible, consistent
with the required BUC
output power, transmit IF
cable loss and maximum IF
output level capability of the
modem.
STAn n = 0 to 12 dB
Certain firmware versions
allow 4 dB steps, while
other firmware versions
allow 1 dB steps.
Set transmit
power alarm
threshold
Sets the transmit power
alarm threshold in dBm.
The allowable threshold
range depends upon the
model of the BUC. Use VLD
to display the upper and
lower limits of the allowable
range for your BUC (see
page 73, View limit data).
If the transmit power falls
below the set threshold, a
transmit power alarm is
generated.
SATn n = value within the
allowable threshold range
for your BUC
n = 0, disables the transmit
power alarm
